Crypto.Hash

Contents

Description

Generalized cryptographic hash interface, that you can use with cryptographic hash algorithm that belong to the HashAlgorithm type class.

import Crypto.Hash

sha1 :: ByteString -> Digest SHA1
sha1 = hash

hexSha3_512 :: ByteString -> String
hexSha3_512 bs = show (hash bs :: Digest SHA3_512)

Synopsis

Types

data Context a

Represent a context for a given hash algorithm.

data Digest a

Represent a digest for a given hash algorithm.

Instances

Functions

digestFromByteString :: (HashAlgorithm a, ByteArrayAccess ba) => ba -> Maybe (Digest a)

Try to transform a bytearray into a Digest of specific algorithm.

If the digest is not the right size for the algorithm specified, then Nothing is returned.

hash methods parametrized by algorithm

hashInitWith :: HashAlgorithm alg => alg -> Context alg

Initialize a new context for a specified hash algorithm

hashWith :: (ByteArrayAccess ba, HashAlgorithm alg) => alg -> ba -> Digest alg

Run the hash function but takes an explicit hash algorithm parameter

hash methods

hashInit :: HashAlgorithm a => Context a

Initialize a new context for this hash algorithm

hashUpdates :: (HashAlgorithm a, ByteArrayAccess ba) => Context a -> [ba] -> Context a

Update the context with a list of strict bytestring, and return a new context with the updates.

hashUpdate :: (ByteArrayAccess ba, HashAlgorithm a) => Context a -> ba -> Context a

run hashUpdates on one single bytestring and return the updated context.

hashFinalize :: HashAlgorithm a => Context a -> Digest a

Finalize a context and return a digest.

hash :: (ByteArrayAccess ba, HashAlgorithm a) => ba -> Digest a

Hash a strict bytestring into a digest.

hashlazy :: HashAlgorithm a => ByteString -> Digest a

Hash a lazy bytestring into a digest.
